IMPROVEMENT IN FRAMES FOR WOVEN-WIRE MATTRESSES.

Specification forming part of Letters Patent No. 170,333, dated November23, 1875; application filed August 23, 1875.

To all whom it may concern:

Be it known that I, WILLIAM J. BODA, of Dayton, in the county ofMontgomery and in the State of Ohio, have invented certain new anduseful Improvements in Frames for Woven- Wire Mattresses; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, making a partof this specification, in which Figure 1 is a perspective View of theupper side of my improved frame with the web detached. I i g. 2 is aplan view of the lower side of the same; and Fig. 3 is a centrallongitudinal section of said frame, showing the position of the Web.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to increase the strength and durability oftheframe of a woven-wire mattress, and to render the same more easilyextensible in a longitudinal direction; and to this end it consists,principally, in the means employed for increasing or lessening thelength of the frame, substantially as and for the purpose hereinafterspecified. It consists, further, in the peculiar construction of theframe, by means of which it is enabled to withstand longitudinal andvertical pressure, substantially as is hereinafter shown.

In the annexed drawings, A and A represent two rails or bars, which areeach connected at one end to or with metal blocks B and B, and fromthence diverge, and at their outer ends are connected together by meansof across-rail, O. With-in the lower side, at the transverse center ofone of the blocks B, is provided a sleeve or housing, I), which,interiorly, has a square opening, b, while upon the opposite block B iscast or otherwise se cured at bar, I), that corresponds to and may becaused to pass into said opening b, such construction enabling saidblocks, with their fIztIll6-S6CtlODS, to be connected together and heldin relative positions laterally, while in a longitudinal direction theymay be brought together or separated to a distance equal to the lengthof said bar 11 without becoming disconnected. Upon the upper side ofeach block 13 and B is, respectively, provided a vertical lug, b and b,through one of which is formed a threaded opening, that receives andcontains a screw, D, while within the other of said lugs is formed arecess for the reception of the end of said screw. A flat head, 61, uponthe outer end of the screw D enables the latter to be rotated, so as topress the frame-sections apart or permit the same to be closed together.Upon the outer side of each cross-bar O is provided a clamp, c, forconfining thereto the end of the woven-wire web, which, when in place,may be distended and any required degree of tension produced by turningthe screw D, so as to separate longitudinally the frame-sections.Theframe thus constructed has sufficient space between its centralportions and the woven-wire web to prevent contact between said partswhen in use, while, from the inverted-arch form of said frame, greatstrength to resist the longitudinal pressure or strain is secured.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1. In combination with the sections of the frame shown,the blocks B and B, provided, respectively, with the sleeve 1) and barI), and with the lugs b and 11, and the screw D passing through said lugb and impinging upon said lug b, said parts being arranged to:

operate in the manner and for the purpose substantially as specified.

2. The hereinbefore-described extensible frame, consisting of the railsA and A, blocks B and B, provided, respectively, with the sleeve b andbar b, and the cross rails G and 0, extending between the outer ends ofsaid rails A and A, all arranged in the manner shown, so as to form aninverted arch, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this13th day of August, 1875.

WILLIAM J. BODA.
